环氧乙烷

环氧乙烷用途

【用途一】
用作有机化工原料及溶剂，主要用于生产乙二醇、乙醇胺及非离子表面活性剂
【用途二】
用于有机合成
【用途三】
环氧乙烷是除草剂丙草胺的中间体，并且是一种重要的化工原料，用于制造乙二醇、乙醇胺、二乙醇胺、乙二醇醚，也可用于生产非离子型表面活性剂。
【用途四】
杀菌消毒剂；谷物熏蒸剂。
【用途五】
环氧乙烷有杀菌作用，对金属不腐蚀，无残留气味，因此可用材料的气体杀菌剂。通常采用环氧乙烷-二氧化碳（两者之比为90：10）或环氧乙烷-二氯二氟甲烷的混合物，主要用于医院和精密仪器的消毒。环氧乙烷用熏蒸剂常用于粮食、食物的保藏。例如，干蛋粉的贮藏中常因受细菌的作用而分解，用环氧乙烷熏蒸处理，可防止变质，而蛋粉的化学成分，包括氨基酸等都不受影响。环氧乙烷易与酸作用，因此可作为抗酸剂添加于某些物质中，从而降你这些物质的酸度或者使用其长期不产生酸性。便如，在生产氯化丁基橡胶时，异丁烯与异戊二烯共聚物的溶液在氯化前如果加入环氧乙烷，则成品即可完全不用碱洗和水洗。环氧乙烷自动分解时能产生世大能量，可以作为火箭和喷气推进器的动力，一般是采用硝基甲烷和环氧乙烷的混俣物（60：40-95：5）。这种混合燃料燃烧性能好，凝固点低，性质比较稳定，不易引爆。总的来说，环氧乙烷的上述这灯直接用途消费量很少，环氧乙烷作为乙烯工业衍生物仅次于聚乙烯，为第二位的重要产品。其重要性主要是以其为原料生产的系列产吕。由环氧乙烷衍生的下游产吕的种类远比各种乙烯衍生物多。五氧乙烷的毒性为乙二醇和27倍，与氨的毒性相仿。在体内形成甲醛、乙二醇和乙二酸，对中枢神经系统起麻醉作用，对粘膜有刺激作用，对细包原浆有毒害作用。
【用途六】
环氧乙烷是用途广泛的合成中间体。主要用于生产乙二醇，还可生产乙醇胺类、醚类、非离子表面活性剂、防冻剂、增塑剂、添加剂、香料、高能燃料、推进剂等。

环氧乙烷制备

(1)氯醇法
以乙烯为原料，先经次氯酸化制得氯乙醇，然后用碱环化而得。具体工艺是：将乙烯和氯气通入水中生成氯乙醇，该反应在耐腐蚀的反应器中进行，氯气、水和乙烯并流通入反应器，在20～50℃和0.2～0.3 MPa下反应，生成2-氯乙醇水溶液，含量一般在6%～7%以下。然后用碱(通常为石灰乳)与氯乙醇反应，进行环合。反应温度控制在100℃左右，生成的环氧乙烷尽快离开反应区，从反应器上部的冷凝口流出，然后汽液分离，蒸馏可得成品。

工艺流程：1、乙烯的次氯酸化反应在温度27-43℃，压力0.2-0.Mpa下进行。所用反应器为塔式反应器。从塔底加入水，在稍上部加入氯气，在再上部加入乙烯。水、次氯酸、乙烯并流向上通过反应器进行反应，得到氯乙醇含量为4%-5%（质量）的反应液；反应副产物为二氯乙烷、二氯乙基醚等。从反应器顶部逸出的气体进入冷凝，不凝气体大部分为未反应的乙烯，除少量放空外，大部分经水洗、碱洗后返回反应循环使用。2、皂化上述冷凝液与反应器中溢出的反应液一起送入皂化水解塔。水解塔温度低于100℃，压力为常压；加入过量10%-20%的石灰乳，氯乙醇在皂化塔中水解为环氧乙烷后，与其他氯化副产物一起从塔顶蒸出；然后依次经初馏塔和精馏塔脱去低沸物和高沸物后而得环氧乙烷产品。消耗定额（kg/t）：乙烯800，氯气2000，石灰1600；同时副产氯化钙3200，二氯乙烷100-150。

(2)氧化法
由乙烯与空气或氧气通过银催化剂于200～300℃和1～3 MPa压力下在气相直接氧化制得。
氧化法催化剂一般含银10%～30％，有效助催化剂是碱金属和碱土金属(如铁、钙等)。常用的载体为α-氧化铝或碳化硅，反应后生成氧化气体，于吸收塔内用水吸收，未反应的乙烯循环回反应器，吸收液经解吸蒸馏而得产品。

工艺流程：新鲜乙烯、空气和循环气体混合后在换热器中与反应器中出来的气体换热；然后加入（2－3）×10-6的二氯乙烷，使催化剂活性降低，同是提高其选择性。该混合气体随后进反应器反应；反应后的气体经冷却后进第一水吸收塔，用水吸收其中的环氧乙烷；未吸收的气体大部分返回主反应器循环使用，少量（10%-20%）经补加空气，并预热后进副反应器反应；由副反应器出来的反应气体经冷却后进第二水吸收塔。第一第二吸收塔；塔顶出来的解吸气体进净化塔，从塔底除去残佘的水；塔顶产物再经初馏塔、精馏塔分别除去轻组分和重组分后，得到环氧乙烷产品。消耗定额：乙烯0.9-1.0t/t,二氯乙烷18kg/t，催化剂18kg，冷却水19t/t，空气6000-7000平方立米，蒸汽0.09t/t，电800-1500KW·h/t。

精制方法：主要杂质是醛类(如甲醛、乙醛)，通过蒸馏装置可使含醛量不超过54mg/m3。其他精制方法有分子筛吸附法，2-乙基己酸处理法和甲醇蒸取蒸馏法等。
